My Top 3 Reasons as to What Went Wrong with Appliance and Storage Array-based Storage Virtualization Solutions

By | Networked Storage, Virtualization | No Comments

n the early 2000’s I was a big believer in appliance and/or controller-based storage virtualization technology. To me, it seemed like the most logical choice to solve some of the most pressing problems such as data migrations, storage optimization and reducing storage networking’s overall management complexity that were confronting the deployment of storage networks in enterprise data centers. Yet here we find ourselves in 2015 and, while appliance and storage control-based storage virtualization still exists, it certainly never became the runaway success that many envisioned at the time. Here are my top 3 reasons as to what went wrong with this technology and why it has yet to fully realize its promise.

10 Characteristics That Help to Define Today’s High End Storage Arrays

By | Fibre Channel, Networked Storage, Storage Systems | No Comments

It has been said that everyone knows what “normal” is but that it is often easier to define “abnormal” than it is to define “normal.” To a certain degree that axiom also applies to defining “high end storage arrays.” Everyone just seems to automatically assume that a certain set of storage arrays are in the “high end” category but when push comes to shove, people can be hard-pressed to provide a working definition as to what constitutes a high end storage array in today’s crowded storage space.

The Challenges of Delivering Inline Deduplication on a High Performance Production Storage Array

By | Data Reduction, Deduplication, Flash Memory, Networked Storage, Solid state storage Flash Memory SSD, SSD, SSD Storage Systems, Storage Systems | No Comments

The use of data reduction technologies such as compression and deduplication to reduce storage costs are nothing new. Tape drives have used compression for decades to increase backup data densities on tape while many modern deduplicating backup appliances use compression and deduplication to also reduce backup data stores. Even a select number of existing HDD-based storage arrays use data compression and deduplication to minimize data stores for large amounts of file data stored in archives or on networked attached file servers.

One of the more difficult tasks for anyone deeply involved in technology is the ability to see the forest from the trees. Often responsible for supporting the technical components that make up today’s enterprise infrastructures, to step back and recommend which technologies are the right choices for their organization going forward is a more difficult feat. While there is no one right answer that applies to all organizations, five (5) technologies – some new as well as some old technologies that are getting a refresh – merit that organizations prioritize them in the coming months and years.

Drawing the Line between Open Source and Proprietary Code; Interview with iXsystems CTO Jordan Hubbard, Part V

By | Networked Storage | No Comments

Establishing a standard as to how an organization uses proprietary and open source code is at best difficult for most organizations. But iXsystems has essentially bet its future on the continued use of open source code in its product line. This makes it an imperative that it get this decision right to continue fostering support for its product in the open source community. This fifth entry in my interview series with iXsystems’ CTO Jordan Hubbard discusses his thoughts on iXsystems’ responsibility toward the open source community for their contributions and how it draws the line between proprietary and open source code.

Effectively Leverage CPU, DRAM and Flash Cache in Enterprise Storage Array Performance, Part II

By | DCIG Sponsored Analysis, Hybrid, Networked Storage, SSD Flash High performance, Storage Systems | No Comments

Providing high levels of capacity is only relevant if a storage array can also deliver high levels of performance. The number of CPU cores, the amount of DRAM and the size of the flash cache are the key hardware components that most heavily influence the performance of a hybrid storage array. In this second blog entry in my series examining the Oracle ZS3 Series storage arrays, I examine how its performance compares to that other leading enterprise storage arrays using published performance benchmarks.

A Primer on Today’s Storage Array Types

By | Cloud Storage, DCIG, Fibre Channel, Flash Memory, iSCSI, SSD, Storage Systems | No Comments

Anyone who managed IT infrastructures in the late 1990’s or early 2000’s probably still remembers how external storage arrays were largely a novelty reserved for high end enterprises with big data centers and deep pockets. Fast forward to today and a plethora of storage arrays exist in a variety of shapes and sizes at increasingly low price points. As such it can be difficult to distinguish between them. To help organizations sort them out, my blog entry today provides a primer on the types of storage arrays currently available on the market.

Fusion-io Acquires NexGen to Accelerate the Process of Data Center Transformation

By | DCIG, Flash Memory, iSCSI, SSD, Storage Systems, Virtualization | No Comments

Last week’s acquisition of NexGen Storage by Fusion-io was greeted with quite a bit of fanfare by the storage industry. But as an individual who has covered Fusion-io for many years and talked one-on-one with their top executives on multiple occasions, its acquisition of NexGen signaled that Fusion-io wanted to do more than deliver an external storage array that had its technology built-in. Rather Fusion-io felt it was incumbent for it to take action and accelerate the coming data center transformation that it has talked and written about for years.

The Two Forces Driving the Evolution (or is it Revolution?) in Enterprise Midrange Array Architectures

By | DCIG, Fibre Channel, Flash Memory, iSCSI, SSD, Storage Systems | No Comments

In May 2010 DCIG released its first-ever Midrange Array Buyer’s Guide in which we covered 70+ models from over 20 vendors. Fast forward just three (3) short years later and DCIG is on track to release not one, not two, not three no, not even four Buyer’s Guides on enterprise midrange arrays but five distinct Buyer’s Guides on this topic! So what has changed in just three (3) short years that DCIG feels the need to produce so many? To understand this requires a closer look at the forces that are driving the evolution and revolution in enterprise midrange arrays.

If you are a regular follower of the DCIG blog site you may have noticed that there has been a noticeable lack of blogging activity on DCIG’s site this week. Unfortunately it is not because I have been taking a vacation, fishing or merely lounging by the lake. Rather I have been locked away in my office completing the background research associated with the upcoming release of the DCIG 2012 Midrange Array Buyer’s Guide due out in the 4th quarter of 2011. Out of that some interesting early observations have emerged.

Time to Refresh the DCIG 2010 Midrange Array Buyer’s Guide

By | DCIG, Deduplication, Fibre Channel, iSCSI, Storage Systems, Virtualization | No Comments

About a year ago DCIG decided to do something completely different in the analyst space: a side-by-side independent comparison of products in a particular market segment in the form of a Buyer’s Guide. The end result of that was the DCIG 2010 Midrange Array Buyer’s Guide. But believe it or not, a year has already passed since that was produced and it is now time to update and refresh that Buyer’s Guide for a number of reasons.
